LEWIS PENGILLY, or s'rocx'ron, cluaroam IGNITION HEAD FOB CIGAR AND CIGARETTE LIGETERS Application filed March 4, 1924. Serial No. 696,767.

declare the following to be a full, clear, and

exact description of the same, reference being had to t e accompanying drawings, and to the characters of reference marked thereon, which form a part of tlllS. application.

'This inventionrelates to electrical ignition heads for cigar and cigarette lighters, and particularly to a head'to beused in connection with that form of lighter which includes a current-carrying cord wound on a spring reel, mounted on the dashboard of anautomobile, such as is shown in my coending application, .Serial No. 685,882, filed January 12th, 1924. The principal object of this invention is to construct the head in such a manner that it may be very easily separated into its vaany other art apt to break or wear out, may be rea ily replaced.

Devices of' this character are provided with switch means automatically closedwhen the head is pulled out of its socket adjacent the reel, and another object 'of my invention is to provide-means for enabling the head to. be withdrawn without said switch becoming closed. This enables the head to be worked on without dan er of any short circuits being made, and wit out having to disconnect any of the wiring at the reel or beyond the same. v

A further object of the invention is to produce a sim le and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of ref erence indicate corresponding parts in the several views:

Fig. 1 is a side outline of a combined cigar and cigarette lighting structure, showing my improved ignition head and switc means.

ters; and I do so that the heating elements, or

A 4 is a section on line 4-4 of Fig. 2.

'Fig. 5 is a longitudinal section of the removable connection-stem of the head.

Referring now more paticularly to the characters of reference on the drawings, the numeral 1 denotes the casing of a springsreel structure of common form, zvhich 'of itself forms no part of my inven- From this casing a rigid tube 2 extends tangentially, being adapted to'be securedto rluliid pro ect through a dashboard 3 or the The ignition head comprises in general a head portion proper, and a stem portion extending at right angles to the axial plane of the'head and adapted tofit in the tube 2.

The head comprises a hollow circular member 4 with a portion 5 concentric therewith but of reduced diameter, the latterport1on having a short hollow stem 6 projecting at right angles to the axial planeithereof. The opposite ends of members 4 and 5 are open and closed respectively, the rim of the former serving as a seat for an insulation disc 7 of mica' or the like, removably held in place by means of a flanged ring or cap 8 having a snug fit on the member 4.

On the outer face of the disc 7 is a heating element 9, secured thereon by screws 10, which project through the disc and are adapted to engage and press against opposed spring members 11 formed as part of strips 12 mounted in spaced relation in an insulation core 13 removably seated in the portion 5.

Adapted to'removably fit in the stem 6 is an insulation core 14, having embedded thereinfor a portion of its length spaced pins 15, projecting beyond the inner end of said core and adapted to removably engage the strips 12 and seat in the; core 13 by reason of circular sockets 16 formed in said strips 12 and core 13, as shown in Fig. 4. I r

The core 14 is longitudinally split beyond the inner ends of the pins 15, one half 17 of the split portion being removable but normally secured thereto as by means of a split-band 18.

The flexible reel 'pro'ect'into the core 14 along the split line, an are secured to the adjacent ends of the pins 15 by soldering or otherwise. this manner the necessarly connections between said pins and cab es may be easily leads or cables 19 from the made and inspected when desiredwithout the use of screws or the like, and without having to bind the same with tape, and 'yet such connections are normally concealed and protected. I

A metal sleeve envelops the core 14:,-

and is removably mounted on the stem 6 with .a snug frictional fit..

This sleeve. has a running 2, and is ada ted to be -inserted therein and withdrawn t erefromat will.

Mounted on .the. tube' 2 adjacent the plane of the inner end 1 of the sleeve 20 when the latter is fully telescoped in said tube is an insulation ring 21, having a spring band 22 extending for a certain distance about the periphery of the ring. One end of this band is secured to the ring and to. a-lead'23 of the wiring of the reel.

" screw, is located in: the ring 21 u'nder the free end of the band 22, and-engages the tube 2. This member 24 not onlygserves as a means to secure-the ring 21 to the tube 2, .but when-en aged by the band 22, closes a. circuit from ead 23 to ground through the metal tube 2, which the circuit to be closed through leads, 19fand element 9.

Slidably and radially mounted in .the ring 1 21 and projecting ,throughthe tube-2 is a pinv outwardly \by the rounded .or tapered end 26 of the sleeve 20 when the. latter is fully inserted in the tube 2. This movement of the pin 25 raises the spring band 22 from contact pin 24, breaking the circuit.

In operation then it will beseen. that as the head as a unit isdrawn away from the tube 2, the switch to the element 9 will automatically be closed.

Should it be desired however'to hold the switch open while still holding the head away from the tube 2,-it is only necessary to unseat the sleeve 20 from the stem" 6, slide it over the core 14 and along the extended cords 19, and press it into a fullytelescoped position in the tube 2.- This, as previously explained will break the circuit. The head may therefore be worked on in a convenientposition without fear of causing any short circuit, and theheating element may be instantly replaced, or the entire structure taken apart for inspection orany necessary ad'ustments-or repairs. lly devieeghowever has still another valuable featurei The element takes an appreeiable'time to heat to the necessary degree, and heretofore it has been necessary to definitely hold the head away from the reel while the element is heatmg'up.

fit in the tube A pin 24, preferably in the form of ,a set In my improved structure, however, the

spring switch-band. .22 presses the pin 25 inwardly of the tube with a'strength greater than that of the spring of the reel tending- 'to draw-the sleeve. 20 in and thus raise the pin and break the circuit.

Therefore by drawing the sleeve out of the tube just a sufiicient distance to cause the switch to be closed. and the pin to project into the tube beyond said sleeve, the latter (to which the ignition head is attached) maybe left in and supported by the -tube-while the element is heating. hen

the element is ready for instant use the moment the head is drawn clear of the tube.

At the same time, should the operator decide not to use the head after the element has thus been heated, all he .has to 'do is give a slight inward push on the head, which of course will instantly open the switch.

' From theforegoing description it will be readily seen-that I have produced such a device. as substantially fulfills the objects of the invention as set forth herein.

'WVhile this specification sets forth in detail the present and preferred construction of the device, still in practice. such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

and contactmeans in the body with which the heating element then automatically engaged.
